Indoor Space

The start with you will need a devoted space for your plants that is you won’t be able to move them around. The ideal place to set up your cultivation would be a space that allows proper air ventilation because growing this plant is going to smell. Especially when the plant is flowering you would want to redirect the air so your site doesn’t start reeking of weed. The best idea would be to start on a small area as the smaller is the growth the less expensive the setup. Make sure the room you choose has adequate space as the plants tend to multiply at a higher rate plus you’ll need space for the equipment too.


Marijuana, like all other plants, also needs certain environmental conditions in order to survive. Temperature, light intensity, humidity, and airflow are all factors that need to be monitored in order to keep your plant healthy through its different phases. You can compare the quality of your product with a respected dispensary such as hibrid to see if it is up to the mark or not.

 Depending on the place you chose to grow your plant, you’ll have to arrange the setup accordingly. If you’re planning to cultivate it in a cold, wet basement you might just have to arrange the dehumidifier or heater to stabilize the environment.


Weed plants need different amounts of light during their different stages. When growing the plant outdoors the sun and the seasons take care of the light but when growing indoors you have to take control of the lighting. The plant needs at least 18 hours of light in a vegetative state and 12 hours when it’s flowering. There are various types of lights available that you can use for your plant. Fluorescent light fixtures are quite popular with small-scale cannabis growers as they are cheaper to set up and do not require a cooling system.

Air Circulation

The marijuana plants need fresh air to survive and carbon dioxide is essential for the process of photosynthesis. This implies that you will need a steady airflow through your grow room. The easiest way would be to place an exhaust fan near the top of the space to suck the warm air out. You can also add a passive fan on the opposite side of the space to bring the cool air in. A complete air exchange throughout the space would occur once every minute or so and would be enough for your plant to thrive. There are other methods that you can undertake like you can set up fans, ACs, dehumidifiers, etc.
